| 摘 要： | 利用NCEP/NCAR再分析资料对1994年和1998年这两个典型旱涝年江淮流域水汽输送和收支状况等进行了诊断分析。结果表明：干旱年该地区主要为南北向水汽输送所控制,而洪涝年江淮流域上空有较强的东西向输送,干旱年5—8月由西、南边界的水汽输入明显比洪涝年少,这是造成该地区旱涝的重要原因,因而在未来的江淮流域旱涝预测中要特别重视西、南边界的水汽输送。

| Abstract: | The water vapor transports and budgets are analyzed by using the NECEP/NCAR reanalysis data from 1994 and 1998. The results show that the Jianghuai valley was mainly controlled by moisture transport from north to south in drought years and east to west transport in flood years. The water vapor inputs in dry summers from the west and south boundaries were obviously less than those in flood years, which is an important cause for droughts and floods in the Jianghuai valley and should be paid great attention in the drought/flood prediction service. |
